Definitions
- the present invention relates to a compound which is useful as starting materials for preparing ophthalmic devices such as contact lenses, intraocular lenses and artificial corneas, hereinafter also referred to as ophthalmic monomer, and a method for the preparation thereof.
- the present invention relates to a compound which has a specific number of silicone atoms and a specific number of fluorine atoms, is copolymerizable with the other polymerizable monomer such as a (meth)acryl monomer to provide a polymer having high transparency, oxygen permeability and excellent stain resistance and being suitable for ophthalmic uses, and a method for preparing the silicone compound.
- silicone compounds are known as an ophthalmic monomer.
- TRIS 3-[tris(trimethylsiloxy)silyl] propyl methacrylate
- hydrophilic monomers such as 2-hydroxyethyl methacrylate (HEMA). Therefore, when TRIS is copolymerized with a hydrophilic monomer, there is such a disadvantage that a transparent polymer is not obtained.
- SiGMA described above has good compatibility with hydrophilic monomers such as HEMA.
- the copolymers obtained from SiGMA have relatively high oxygen permeability and high hydrophilicity. Recently, higher oxygen permeability is required for an ophthalmic polymer so as to be used continuously on eyes for a longer term. Polymers obtained from SiGMA do not have sufficient oxygen permeability.
- Patent Literature 1 describes a compound represented by the following formula (a).
- the weight ratio of the Si-containing moiety i.e. bis(trimethylsiloxy)methylsilyl
- the weight ratio of the Si-containing moiety, i.e. tris(trimethylsiloxy)silyl, to the whole molecule is 60 %.
- the compound represented by the formula (a) thus has the higher weight ratio of the Si-containing moiety and, therefore, gives higher oxygen permeability to ophthalmic devices.
- Patent Literature 2 describes that the compound represented by the aforesaid formula (a) is prepared by a reaction of a corresponding epoxy precursor and methacrylic acid. There is such a problem such that many side reactions occur and the physical properties of the resulting copolymers vary.
- Japanese Patent No. 4882136 Paten Literature 3, describes a compound represented by the following formula (e) and an ophthalmic lens prepared from a polymer having repeating units derived from the compound.
- the polymer obtained by polymerization using the aforesaind compound as a monomer component has poor mechanical strength, and a reactivity of the polymerization of the compound is poor. Further, a stain resistance of the polymer obtained is insufficient.
- a silicone having a tetrameric or more structure is thought to be preferable in term of oxygen permeability and, in particular, a silicone having a tetrameric or pentameric structure is thought to be more preferable in order to balance between oxygen permeability and strength of the copolymer. Therefore, development of a method for preparing a silicone monomer having a tetrameric or more structure with a high purity is desired.
- Patent Literature 4 describes a method for the preparation of a silicone compound represented by a following formula (b), comprising steps of anion-polymerizing a cyclic siloxane in the presence of a lithium trialkylsilanolate as an initiator and, then, reacting the reaction product with a chlorosilane having a (meth)acryl group, such as 3-(2-methacryloyloxy ethoxy) propyl dimethyl chlorosilane.
- a chlorosilane having a (meth)acryl group such as 3-(2-methacryloyloxy ethoxy) propyl dimethyl chlorosilane.
- silicone compound obtained in the afore-mentioned method is mixed with a hydrophilic monomer, such as 2-hydroxyethyl methacrylate, turbidity occurs sometimes. Further, a ratio of terminals of the silicone chain blocked with the chlorosilane is not high.
- Patent Literature 5 describes a method for preparing a silicone compound represented by the following formula (c) by esterifying (meth)acrylic acid or transesterifying (meth)acrylate with an organopolysiloxane having a hydroxyl group at the one terminal, wherein r is an integer of 3 or larger.

- a monomeric compound having a fluorinated hydrocarbon group was developed in order to increase oxygen permeability of its polymer or add stain resistance to its polymer.
- Japanese National Phase Publication No. 2003-516562 describes a method for copolymerizing a hydrophilic monomer, a monomer having tris(siloxysilyl) group and a monomer having a fluorinated hydrocarbon group.
- Japanese Patent Application Laid-Open No. 2008-274278 and Japanese National Phase Publication No. 2013-507652 describe a fluorine-containing silicone monomer having a siloxane chain to which a fluorinated hydrocarbon group bonds as a side chain and a polymerizable group, represented by the following formula.

- Patent Literatures 8 and 9 describe that the aforesaid compound is prepared by subjecting a fluorinated hydrocarbon-containing cyclotrisiloxane to a living polymerization with alkyl lithium or lithium alkyl dimethyl silanolate as an initiator, and capping the terminal with methacryloxypropyl dimethyl chlorosilane after all of the cyclosiloxane monomer reacts.
